It is difficult to start and it is more difficult to continue.
Time reveals if you have enough of determination and if the case, the project, the issue or your relationship is really important to you. When we start we are full of hope and expectations of success we achieve when we will finish. But there is a temptation to resign every time we meet the obstacles or difficulties. So do not give up, what is really important could need more energy than it was expected, but it is worth it and be fruitful at the end.
Have a nice day, a lot of positive motivation and remind yourself why have you started it.
