If we are doing something for a genuine purpose then we do not need any kind of motivation to work towards our goal. The goal itself is so pure that we do not want to stop until we achieve it.
Everyday take one step closer towards the goal and see the difference in your daily life and the thoughts our brain processes every single day. We get full of energy and hope by just visualizing the results or the goals that we want to achieve.
It is true that not every day is the same day, sometimes the days are not in our favor but it doesn’t mean we should not hope for the next day to be for us and work for it. Take a break, give yourself time to recover again get back to work and finish what you have started.
Our motivation gets faded as we have an external motivation to keep working. Outer push or motivation works as fuel and it needs to be refueled time to time. Hence, we will be tired and exhausted after working for a few hours, because we are not doing the right thing, we must be doing something we really admire and wish to do.
My motivation is my work and the goal which is going to be achieved by working consistently and honestly!
