When making a difficult decision a good place to start is weighing up the pros and cons.
Take some time and really think about it.
Let’s say for example you were deciding whether or not move to a new city. The pros might be things like getting a fresh start, more opportunities and challenging yourself. The cons could be a lack of familiarity, time lost having to start over and leaving family/friends behind.
You could also ask yourself questions like:
Will the short-term advantage benefit me in the long-run?
I think if you regularly find yourself caught between making a change and doing nothing, you might just be afraid of trying something new or making a mistake.
In those cases it might actually be better to throw yourself into doing the the thing you’re unsure of because at least you’re giving yourself the opportunity to grow, develop and explore.
