To be successful in any field, one have to make efforts, of course. But what does making efforts mean indeed?
First, putting a lot of time into what you want to acheive. No matter how efficiently you work, working only 2 hours a day will never lead to success. Taking a rest very often does not contribute to success.
What is needed to working long time? Not thinking anything else.
Many people say that if you are not motivated, imagine your future. If you suceed, what will your life be like?
This strategy will work in some time, but spending (or wasting) a lot of precious time considering your future and not working at this time will never get you anywhere close to what you want.
When working, work with your mindfullness. Don't pay attention to anything else.
