PASSION V/S DISTRACTION
If there's something that's constantly on your mind, either work your way towards it or away from it.
We all know how to differentiate between good and bad. But we often don't ask ourselves the question that whether what we are doing is good or bad. If there's some thing that you have been doing for hours and hours together, ask yourself whether doing this will give you happiness in the long run. For example, if you are on social media most of the day, you will be happy in the short term, but in the long term it will hinder your studies, work and your whole life. This is thus a distraction. Get rid of its before its too late.
And if the answer to your question is that it can lead to happiness in the long term, then continue with it. For example, art. If you have a passion, then try your best to make it a career option. It is the best way to earn money while being happy. And if you can't due to whatsoever reason make it your career, don't give it up. Continue it to keep yourself happy and satisfied in life.
