We all have our strengths and areas for improvement. We all have our needs (and wants). Any of these change, from minute to minute to time periods during our lifespan.
Go after what you want. I fervently believe you should.
At the same time, you will only best serve yourself when what you want complements what you need. If you’re pursuing what you want when it interferes with what you need, you will do yourself harm, and the benefit of what you want will be lost, likely replaced by pain, disappointment, wasted energy, etc. (This is not known fact; this is a hypothesis of mine. Challenge it, try it on with different scenarios, see if it fits. It has passed my tests so far. Let me know what you think.)
If what you want is at odds with your current needs or where you are at this point, do not give up on your want! DO NOT! Is there another way to satisfy your want? Can you “backburner” your want until your want and needs are aligned? So much of life is timing. Very little in life requires the immediacy we often assign it.
Know your needs: know what you need at this time in your life. Know what you want. Be aware enough to know the difference, smart enough to know which needs and wants align, and disciplined enough to choose to pursue those wants which complement your needs now.
