Be humble and realise you're a graduate in a sea of graduates. You got a first? Good for you. So did a countless number of others . You need to realise you are ordinary on paper. You lack basic skills and will need time and effort of colleagues and the company to fill those gaps. You'll need tonnes of training, lots of patience from colleagues that think you work too slowly. You have little to offer except 'potential' which may never be fulfilled. You could be one of those useless graduates (I've met several) who just can't operate in the real world.
Focus on "learning your trade." Focus on improving your skills - be that programming, managing meetings and stakeholders (usually with opposing interests), presentation skills, networking and soft skills, project management skills etc Worry about salary later. Be good at what you do. You'll grow in confidence, command projects, command interviews. It takes time when you have almost no workplace skills. You're at the bottom of the chain and it's time you realised what that truly means.
I took my first job at £19k. Pitiful yes, but I got involved in tonnes of stuff well beyond my role. 2 years later it helped me get another lowly paid £29k job which was a 1.5-2hrs commute one way. Imagine all that travelling for a job that didn't pay a great deal? Where's that killer wage I'd been waiting for? But alas, I knew this was gold. It was a job with a great company, the responsibilities in the role were fantastic with tonnes of scope.
15 months later, I was accepted for two jobs. One paying £63k, the other £52k. Both at the same company but in different areas . I took the latter. Why? Because I know it has better development in line with my career aspirations, and I know I'll get better skills from it. I know in 18-24 months I'll be genuinely eligible for contract roles that pay £80k+. 5 years down the line it will be six figures - I've seen it and know colleagues that do it. It's not something out of reach. In fact, I'll probably want to start my own business before then. My brother earns over £160k, where did he start? He was stuck on £23k for 3 years too!
My point is have a medium to long term view of things. Position yourself in your career path toward your goals and aspirations - this takes time and effort. I took on extra work, I paid for professional courses and studied outside of work, I travelled ridiculous distances. Starting out is hard. You know very little about your industry and certainly haven't developed a map. The road ahead is long, try to get value out of things you do rather than focusing solely on a number.
