Hello

I want to be more motivated
for examle i have times during the day when I am in the tram for examle and I feel very motivated to do thins that I plan, and that would bring me money.

but when I come home, turn on my computers and start doing job that I should start I instantly loose motivation....

How to gain greater(bigger) motivation?
