People need to choose their goals and then work towards them, very few goals can be achieved by not doing something to actually achieve them, but it depends on what goals people have.
I think some of the time, it's important to realise that goals are often not immediately achievable and even when working towards them, other things may get in the way and not always go the way you want. I believe its important to be able to adapt to those new situations, more than anything else.
Some people never achieve their goals but are happy all their life, and some people do and then find that without anything left to work towards they feel lost and just make new goals. Of course there's nothing wrong with that, I just think it emphasises that in addition to goals and ambitions it's important to have something else to hold on as well, and not do what a lot of people do and refuse to be 'happy' until they've achieved their goals.
I certainly have many things I hope to have accomplish, I have no idea how long they'll take, probably longer than at times I'd like to, but in a way things do happen in their own time, but the difference is I still have to do something to make them happen.
