First some background...
I am a hard worker (I know aren't we all)...but really I am. I am motivated to always do a good job. Throughout my career I have always ensured that any and all tasks are completed and I have never missed a target date...ever. The quality of my work is very good and I base this on a lot of my customers (other employee's as well as my managers feedback). I'm in the manufacturing industry but I work mainly on the software / documentation side. All my work comes with a good amount of documentation including manuals, cliff notes, videos, we use SO Teams, etc. This ensures anyone who picks up my work will understand it whether they want to use a tool or edit that tool.
After a LONG time with the company (as I don't like jumping ship - I am old school and committed). At my current workplace I climbed the ranks a little bit not too much (Team lead, supervisor, supervisor II (lead two departments). The time has come for me to find new work (company is not doing so well).
I have finally started pursuing other employment and I have had some opportunities but I notice something about myself. I seem to always short myself...I don't want to say I am a negative person but I always feel like I short myself when it comes to salary as well as explaining myself to different employers (the work I do). I feel like I am not confident enough and I am not that great of a public speaker. I can do it I just don't care for it that much.
My friends and family always wish me luck...and they top it off with "Don't sell yourself short"..and my response is always "Oh don't worry I won't." But deep down I feel like I do...ALWAYS. I feel like I short myself not only in terms of money but what I can bring to the table. I cannot say I am at the top of my game when it comes to the latest technology...but what I am capable of is getting work done and learning that technology. That is to me talk is cheap but walking and doing the work is what makes me (and I feel others) more important. But I always seem to lose this battle.
What steps can I take to stop selling myself so short and add confidence to myself. I am not the sharpest looking tool in the shed and I know looks help but aside from looks what other things can I do to increase my confidence...because I know I can do it...but how do I let others know I can do it and have confidence in me?
I am asking this because I am in final negotiations with a company that I have now gone on various interviews for three times now. They want to see me one more time but they want the main owner to talk to me. I am worried I will not present in such a manner that guarantees my job.
