One thing I learnt in life is hard work means nothing. I seen people work there asses off with 10 times less the salary. I seen people do nothing with a decent salary. I've seen people taking on work or giving out work and no one really pays attention. It's not about how hard you work, obviously that's a small factor you can't be lazy. But it's about making smart choices and investing as well as what information you have. Most people in my field of work just lie about their previous salary, lie about their previous experience etc. If the hard working people I know knew you can simply lie their lives would change.
I've lied about many things I'm a contractor. I've lied about how much work I can do a day so I can have a relaxing job and my contract last longer so the work never runs out. I could do my job in 3 hours easily but I pretent it's a challenging job to the managers. I've lied in my CV to get higher salaries when job hopping, I simply research the job needed, nowadays you have courses and internet to get you upto standard, it's all basic stuff just have to use terminology so you know what your talking about. I've worked with people doing the same job as me with the same quality and target expectations but they are on a much lower pay etc. Like everything in this world it's all a game a hustle, from jobs to, investing, to property market and etc. You need to know how to navigate and hustle in this world It's all about the information you know and not how hard you work.
