Regarding goals, I´d like to tell you something that I find very interesting. If you are unable to achieve your goals, you should know that there is absolutely nothing wrong with you.
We all have something deep inside that thwarts our best efforts to change: our subconscious wants us to live with what we know, and anything unknown to us becomes scary to it. It's a basic survival mechanism. You managed to keep yourself alive so far in life.
Therefore you must be doing something right. Changing that may bring you a different and possibly unfortunate outcome (at least from your subconscious mind's standpoint).
In order for you to see what I´m talking about, I need you to please do this exercise for me. To understand what I'm talking about, try the following.

Plan to do something new.
Something safe but new. Go to a karaoke bar and sing. Take a different route to go to work or to school. Sit on a different place at Church. Wear some garment that you haven't worn in a long time. Talk to a total stranger. Sit in another chair at home. Sign up for a class about something totally "unlike you": knitting if you are a guy, or carpentry lessons if you are a woman.
When you do something different, you will feel mildly to greatly uncomfortable.
It is your subconscious´ way of telling you: "Hey! Be careful! You are in a new (and maybe dangerous) territory" and your stress levels will go up.
If you get anxious about little things like that, how would your subconscious mind react to a major life change? The answer for this is that it will probably take it poorly and it will try to sabotage your efforts.
Then you wonder. "Why do I sabotage myself all the time?" Now you know why.
You may wonder "Why do I sabotage myself all the time?" Now you know the reason.

If you try to change something about your personality or behavior, your subconscious mind will reject the idea of changing, because it is an unknown, even if the unknown is for your own good. The unknown may not be safe and your subconscious mind's goal is to keep you safe.

That force of your subconscious mind is called a belief system and it protects you from change.
On the other hand, when you meet someone who has achieved all of the things that you want to achieve, you may think something like this:
What is wrong with me? How come I can´t be like him/her? You may want to be like this person, and also would like to do the same things they did to get there.
You may want to be like this person and to do what they've done.
But your belief system will make it hard for you to move in that direction.
There´s nothing wrong with you, every time you want to change something in your life, your belief system will resist you.
It feels safe to be where you are right now. Change is scary to the subconscious mind.
The key questions here are:
1.- Where does that belief system come from?
2.- Is there a way to change?
Your belief system comes from everything that you have learned as a child, from your parents, how your parents lived and what they taught you, teachers, siblings, peers at school, grandparents. Etc.

You belief system comes from your childhood experiences and the people who influenced you: your parents, teachers, siblings, classmates, grandparents, etc.
Yes, there is a way to change.
Your belief system (and mine too) wasn´t created overnight, and it can´t be removed overnight either.
Your belief system, like everyone's, wasn't created overnight, and it takes time to adjust.
Right now, we are achieving in life all of the things we are programmed to achieve, nothing more, nothing less.
Right now, we are achieving the goals we were programmed to achieve, nothing more and nothing less.
This involves your relationships with others, your confidence level, your economic situation and your job situation.
Personality wise, studies have shown that your own brain chemistry has a lot to do with it, more than your belief system.
Why some people are very successful, or very rich? Or always ill? Why some people are always late? Or always in accidents? Why some are always being abused by others?
Each person has a different belief system. That's why we have the life we do; it has nothing to do with luck.
If you are not living the life you want, you can change your belief system. That will change the events around you, believe it or not.
This website describes much of what I know about people´s belief systems, about making changes to it and about achieving the life you´ve always wanted. Enjoy the journey!
