jack of all trades, master of one

people give me too much credit. well, they have too much trust in my abilities. its understandable because most of the time, i am able to deliver what they ask for. i may not be the best person for the job but most of the time im good enough when there's no one else to go to. thats why ive always seen myself as playing the role of the back-up. but thats just it, im supposed to be just the back-up. the person you can always rely on when there's no else to turn to. i should be the last resort, the last line of defense or something like that. and i know what im capable of thats why i dont panic that quickly. when i can see that i can pull something out of my sleeve, i dont worry about failing or not accomplishing the task. i can always see a way out or a way to fix things or a way for things to push through. i never give my best at anything because i dont need to. im not there to impress anyone. im just there to make sure that the job gets done. once its done, im gone. no need to stay a second longer. thats the role im supposed to be playing. thats the role i should see myself doing. thats the role i should stick to. nothing else. i found comfort in being that person and i shouldnt aim for anything more for the simple reason that i think being the jack of all trades is the one i should master. i think being this person is what i can be good at. being an expert in a particular field will probably bore me or i wont be able achieve such a level because im not meant to master anything.
