Don't bite off more than you can chew!

I try to do everything but, in the end, I do nothing.

Recently, I’ve realized that I don’t have enough time to do some things that I love, for example; studying English; working out, reading books etc. I’ve worked every day for the last forty days except for 2 or 3 when I got some rest. It's true! I have a little more money but that can’t buy me any rest. When I can take a rest on a day off, I don’t have enough energy to do any of my hobbies.
Some months ago, I bought a multi-station machine (the kind you can find in a gym ) because I wanted to start to exercise. Many people think it’s a great way to relax when one is stressed. But nobody tells you that it’s really hard to keep to a schedule of exercises. The machine already has cobwebs!
On days off, I usually sleep, watch TV, sleep, sleep and watch more TV -  it's terrible! I feel so lazy.
My friends tell me to give up my job, but I don't want to; it’s the first real job (real job) I've had since finishing university. Because of it, I’ve learned a lot of things and I’ve travelled throughout my country.
I probably have to accept that this is the life of a worker or maybe ''I shouldn't bite off more than I can chew''.

Well done!  Keep up the good work.  I have not heard of a "multi-station machine" before but it may be a jargon expression in the keep-fit industry.  We have "multi-gyms" in the UK which may be the same - I haven't checked.  Check also my punctuation changes.  Kind regards, Michael
