Forget all your goals. Kill every dream you have.
First learn this:
Earnestly, as a young man or woman, consistently achieving the act of doing and the ability to DO is what your goal should be.
If you seek improvement of life quality and a renewed sense of self - you must first explore the greater world around you in an effort to squeeze out whatever secret juices of inspiration you can. This secret juice comes in shifting forms and can be defined as the many points of inspiration that allow you to act in perpetuity while filling you with joy.
Doing so might sound simple, but the environment one requires to actually start creating and acting to their own benefit arrives on a person-to-person basis.
This means that it's an individual experience and stems from an individual source.
You must look at yourself as a situational genius - an ultra-capable maven and master creator that needs the perfect environment to allow them to excel. You need to find the environment that feeds into your skills and talents - and you need to aggressively pursue going there, getting yourself in that perfect room.
The power of the inner mind is great, but it is largely overrated when pursuing long-term goals.
Willpower should never be used as your consistent source of power. Why? Because willpower is sapped by imperfect spirituality and the stresses of everyday living. No one is beyond this, and even if you are - this will cost you long-term.
You need something more potent, something that is available to you freely and at all times - like fun, or pleasure, or interest and curiosity.
Don't look at what's smart to do and, for God's sake, don't look at what others think is smart to do - look at yourself and build an understanding of where you feel the most powerful and energetic.
And go there.
What do you interface or engage with that gives you that jolt of inspiration and energy effortlessly?
Find that. Do that.
Everything else will show itself during the process of doing it.
