Persistence is important when u r working on a project/goal that requires alot of time and effort. It can be easy to get discouraged/lose motivation when u r facing challenges, but those who are persistent are able to keep going and push through to reach their desired outcomes.
Trusting the timing of things can help us let go of our need to control outcomes and instead focus on what we can control, such as our attitudes and actions. It can also help us have faith that everything will work out in the end, even if we can't see how at the present moment.
