Life is hard
Eliminate the feeling of reluctance. When the offer comes when you are working, then don't say yes until you really want it. It's also about how you manage your time well between desire and work. If you yourself feel you have not completed your work, then as much as possible do not do other activities that make your work hampered and finally late.
How do you believe something is very important. For example, you are a final year student who wants to graduate on time. Then your beliefs must be really strong. Your beliefs that will get you to get what you want. Don't mind how other people think you are not capable, do not be hooked so you are easy to feel down. Don't let other people take over your beliefs and replace them with fear.
A worrying life, a fearful life, or a happy and peaceful life, are all in your hands. You are the driver of your own life. Whatever you feel in your life, then you also take part in it. You only live in the life that you created yourself.
