Have you been really under pressure with work before?
Recently I have been stacking up deadline after deadline. It has felt as soon as I have got into a job then another "urgent" task comes along.
It had been getting me down. Not so much how busy I was, as I don't mind that, just the fall out of when I suggested other projects would have to be pushed back if I get new tasks thrust upon me.
Then I had a realisation. It didn't matter how stressed I got about the situation, I could only do what was in front of me at that moment. If deadlines got missed due to other work being given to me then there wasn't a lot a could do about that.
By allowing myself to be a bit kinder to myself I have now created a little space in which I can be busy but also more comfortable in understanding that I am doing my best at this current point in time.
What are you being too hard on yourself about? Maybe this is a chance for you to ease some of that self pressure too.
