If you want to talk about fate, this is too big. You were born on the earth, as a human being, not as a plant or tree. This is also part of your destiny. Get rid of the impossible completely. Your birth and your past are facts and cannot be changed. What can change is today and the future.
I think what you want to ask is how to change the current living situation? This is doable.
Having a strong belief is the premise. People without faith cannot accomplish anything, because nothing can be done without encountering resistance and setbacks. You need a strong faith to keep you from falling.
In the future, you should be stricter with yourself, don’t make excuses for yourself, and don’t compare yourself with those who are inferior to you. For example, if you want to eat snacks during weight loss, give yourself an excuse: a snack does not have many calories, so I can ignore it. Don't let things like this appear in your life, because your unsatisfactory situations are often related to such "ignoring".
Look at things around you with tolerance. People with a broad vision will not retaliate, care about others, and will not use their own standards to measure others. Recognize and accept individual differences. This is important because it will pave the way for your success instead of making enemies. Seeking common ground while reserving differences will accumulate a lot of good karma.
In the end, only by giving up can you gain. According to the law of conservation of energy, if you get a kind of energy, it means there must be work done. In other words, you must have consumed additional energy. Don’t think about a successful career, a harmonious family, successful children, good health, and being young and beautiful. . . . . You have taken advantage of all these beautiful things in this world. Human time and energy are limited. This is part of fate and you cannot change it. If you want to live a long and healthy life, you must give up an overly hard career; if you want to devote yourself to scientific research, you must reduce family reunions; if you want to travel around the world, you cannot take care of your elderly parents; if you want to be in good shape, you cannot indulge in delicious food. In short, you have to think about what you really can't let go of. Once you decide, just go for it and stop worrying about gains and losses. Every successful person actually has regrets of one kind or another, because they have also made choices. However, what outsiders see is mostly the side they get.
