I found it interesting when you said ” I feel I need to be something more, something great”, I have fallen (and still fall) into that trap occasionally. I have a security job on a military base, which is protecting people, so quite ‘important’, but I’m a low rank and it’s very mundane sometimes and I do often think ‘shouldn’t I be doing something more/better than this?”, the magic word there is ‘shouldn’t I?’, and where does that ‘should’ come from? It comes from what you THINK other people are expecting and/or you start comparing your life to others who seem to be more ‘successful’, but my job is 4 days on/off, which provides me with a lot of free time, very cheap rent, free medical/dental and a pension, plus I get on great with everyone, and it gives me the chance to do charity work, so on balance am I really worse off? Ironically my previous job was in HR, which I absolutely hated!!!! The pressure, the stress, the phone-calls, emails, in-tray building up, customers complaining, long hours, in hindsight I’m very glad to have left! Keep positive and good luck!
