Cry or be optimistic, your choice
I would argue that it is much better for a person to be optimistic than to cry. If you think about both scenarios, you may get nothing from crying about an issue or hoping that it'll be resolved but your state of mind influences your decisions and your decisions determine whether things will go well or worse.
I am someone who is naturally self motivated, I frequently wake up without power, but I am still confident that I will eventually finish what I need to do for the day, week, months and my yearly goals.
We don't necessarily have to know everything about our plan, we just need to believe in it and continue to trust the process until we have reached our goal. If we only wait until we have a map that tells us exactly what to do with a hundred percent guaranteed victory before we take steps towards the goal, we are sure to remain in one location until we are dead.
In many instances, what we may need to do to solve our current issue will not there itself until after a lot of time has passed. You might bump into solution when you least expected it.
What I can tell you from what I know about handling situations in life is that you will you will find peace when you no longer ask yourself how will this happen every five minutes?
That question in of itself puts you in a state of stillness. This state of is so personal that I cannot even describe it to people who look for logic. Logic is good for mathematical proofs and for all the scientists at that lab but cannot always be dependent on as a way to actually live life or deal with all the unexpected things that come into your life. Something things just don't make sense and that's when we say "the math isn't mathing"
Sometimes I forget what I’m waiting and hoping for but that doesn’t change how I feel about it. An example of this is when you're at the station waiting for a bus, you have no idea what time it will arrive, but you know it will. Even for today's Uber rides, the rider could cancel the trip after you've waited for 10 minutes. What do you do then? Cry or look for another ride?
I've been through so much but I have decided not to change from being an optimistic person, because I know by experience that pessimism will slow you down and make you question things you're supposed to be acting on.
