There comes a time in life where you need to decide. When enough is enough. When it's time to realise that you're the most important person in your life and that you choose the terms of your (work) life.
In our contemporary society, humans are programmed to be driven, career-oriented and not only to be good at what they do, but reaching for being the best. Yet here comes the problem: people with power (might) take advantage of it.
Sometimes it's the expectation of being available 24/7 or of not providing enough team members, requesting you to do tasks which are definitely not in your contract (please, serving coffee?) or no acknowledgement of your achievements, credit of your work to someone else, it might be even sexual, physical or psychological harassments or degrading you infront of others in order to show "who the boss is". This happens everywhere and all the time. But especially in your working environment, there are places with the concept of ignorance, power abuse, and rather the strategy of burning employees instead of building them up.
But listen carefully: You have the power. Now claim it back.
When deciding that you are the most important person in your life
Yes, right. You are the most important person in your life. Nobody owns you and nobody decides over you. The moments of disrespect are done.
Now here comes the thing: At whatever stage in life you are, you can start the change now. It might be hard in the beginning to figure this out. It's a challenge to find out who you actually want to be and what the expectations towards your career are. Taking the step of quitting your job, one which gives you a comfort zone of financial security, it's not easy and also not a must! There are enough jobs which are fulfilling and working freelance or build your own business is not the ideal way for many people. But in case this is a profession or a working environment which doesn't fulfil you or even disrespects you as a person, you need to leave.
Never forget: It's your life and you make the rules.
