If you have got a passion, then follow it.
The most important thing in life is to do things that interest you, that inspire you. Don’t just do things because your parents did them or for a decent salary or job security. Those aren’t unimportant – but you’ll get them if you do things which really give you a reward in life, which motivate you and where you’re giving your best.
