You don't need to worry about others. You should focus on yourself because it is your life and not theirs. Don't let anyone influence how you should live. You should decide on what you want to do.
Always be open-minded on new things! There is always something new to learn every day. You can never stop learning until the day you die. Your knowledge is your greatest asset that no one can take from you.
It is great if you can find yourself a mentor who can teach you everything in life. Mentors are people who can show you many things in life because they have experienced many things before you.
No one except you is responsible for you life. You can win in life or lose in life. Which one do you want? No one is going to force you, but you have to be the one to decide.
