What do you do in your spare time? What do you want to do? What can you do?
Fill these answers with one word; Create.
Create art, create poetry, create dinner. Make something with your time.
Life should be a process of learning things, perfecting them, and forgetting the words. Do you have something you like doing, knitting, sewing, painting? Stop wasting time and fill time with reading how to do it better, watch videos on doing it, read a blog on it. Now take the inspiration and follow through with action. Make something, make 5 things, make a thousand things, then make nothing. Once you have mastered making it without thought, you are ready to do something new.
This is the process of mastery. Do this and grow. Do not be a specialist, do not be a coin, having only one or two skills leaves you shallow. Expand and conquer everything, your mind is a beautiful thing, now plant the seeds and tend your Eden.
