Assalamualaikum wbt :)
Great courage comes not from feeling great while everything goes well. The greatest courage comes when you feel great despite constantly being tested or running through a complicated situation. What is courage if we do nothing much to test it? It is the ability to cultivate a mind that stays calm in the middle of the storm which is much coveted by those who wish to become great. while so many things are running through the mind, many imagined the worst thing that could happen. However, have you noticed that most of the things that you worry about in the past didn't actually happen? Worry is like a rocking chair, it gives you something to do, but gets you nowhere. All worry does is elicit unpleasant emotions and hinders you from truly enjoying the present moment. The future is uncertain, so live in the present, live the moment as it occurs to you. Take control of your worry and feelings, because if you don't, it is possible to go sightseeing in Paris and still be depressed. Take control and you might feel happy just walking through your home garden.
I am not suggesting you to ignore all the troubles that might be looming in the future. I am just asking you not to ruminate about it again and again in your conscious mind. Put it in the back of your mind and solve it when the time comes. I don't have much experience in cooking, but i know that there is such term as 'slow-cooking' using the oven. I have observed chefs in cooking shows put some of their stuff in the oven, let it slow cook and sort of forget about it for a while until the time where the timer comes off. While waiting, the chef would tend to other things that needs present attention like cutting and frying. Uncertain problems that might occur in the future, instead of being tended to as in frying, should be let in the oven to 'slow-cook', while the current things in the present should be attended with your attention. It is not ignoring, it is putting in the back of your mind and live your daily life paying attention to the present. If it helps, put it on a note to remind you, and let it be. You are not procrastinating but letting time find solutions to your problems. You will be surprised that as you live your day, solutions will come from the most unexpected sources. The great thing about putting it in the back of your mind or your 'oven' is that the problems or issues will slow cook and by the time you get it out, it is cooked, or you might already have the solution to the problems.
Weird analogy, indeed I know. Especially from a person like me who doesn't cook. But that's what got into my mind as I watched cooking channels. So, cook all your worries, and live your life in the present!
