Low self esteem will ultimately lead to depression. Deal with dysfunctional thinking by asking yourself things such as, what evidence do I have that I”m a failure? Would other say this about me? Does believing this about me make me feel good or bad about myself? Discover and pursue your goals and your passions and keep in mind that you can’t become an expert over night, you become proficient with practice. Remember that failure isn’t getting something wrong, it’s giving up on yourself that defines failure.
