If we do not set goals, we run the risk of stagnating and that one day we wonder what interesting things have I done in my life? What would I like to have tried? What important things have I achieved?
On the way to being a successful person we are always going to encounter many obstacles, there are going to be difficulties that we will have to face, and practically that is the only reason why not everyone achieves it.
When you have a clear goal and you decide to get to work on it, you cannot let others interrupt or interfere, you must protect it as if it were your greatest treasure. Saying "no" when necessary will keep you focused on your thing. The best thing to avoid being distracted is to establish daily times and routines.
