It is really hard to tell if you are working hard on the thing you like. You may pretend to be loving it while the fact is that you just do it with no concrete goals. Or simply you are only a follower but not the master of your own.
We are not a kid any more. This requires us to analyse, judge and act on our own. No one can fully replace us doing what we like. If we like to be something we have to work hard. Roma was not built in one day. You got the goal, you go for it even though there are unexpected obstacles ahead of the road.
Excuse me! Wake up! You have to do what you like, but do not always change the goal. If so, you probably have no connection to success. Today you want to learn painting, next week you want to lose weight, and next year you decide travelling around. Some goals can be executing simultaneously, while others can be merely done one step at a time. Systematically, you need to plan and act well. If not, you are surely to screw up.
Thanks to god, we have mind and body to work together. Do not blame what you cannot, blame how lazy you are. Please, save the time and do it right now.
