everyone thinks that you should take every opportunity that comes but if you do that your entire life would be new things and you wouldn't have time for your old friends your family
your entire life would be told in a story like this: "and then they tried this, and it didn't work out. and then she tried this, and it worked out very very well. but then she tried this, and it ruined the last one."
of course, you should totally take chances and opportunities. but i believe you shouldn't jump on each train as it comes. you might fall off.
