I was too inconfident...

After 4 years of computer engineering, i'm still not confident of working for people... My first job offered to do a 3 months project in NUS was blown off because i was overwhelmed by the allowance given... it can round up to 10k for 3 months... the money is so big and the project sounded difficult.. hence i was really afraid that i can't do it, even with help... In the end.. i lost it.. I felt so disappointed thereafter and started to wonder if I can ever find a job or not.. what kind of work can i do..?
