There would be many ups & downs in markets & life. Staying the course is one the best advice I can give to you.
Don’t get carried away when you’re doing well.
Don’t be depressed when things aren’t going well.
Just try to stay the course. Do your best. Work your best. Nature has its own way of rewarding.
Giving your best is never a waste of time & efforts. Sooner or later, you would ALWAYS be paid back thousands of times for giving your best.
I speak this from personal experience as well as multiple observations in friends & family.
