It took me a while to realize that one part of my life is gone and I MUST watch in future.
One way is to understand that the answer can be to live NOW. We cannot change the past and the future is not here yet. NOW is where it is at. I am old enough to have lost parents and a brother and can tell you that watching the future is too late. Live NOW.
But do so in a quality way, and be aware of the outcomes of your actions on everything. What I mean is we all can make or ignore decisions all the time. I believe one should conciously make the best decision you can for a quality outcome.
It is easier to do what is expected, but largely I have rejected that and make my own decisions on things that are important to me. Hence I changed my life completely, leaving Australia and a well paid corporate job to do something what is more useful to real people and satisfying to me. There was a price for this of course.
I am really enjoying my new life in Poland. For example, the fact that roads are poor, means cyclists are safer. In Australia we have great roads and cyclists are despised by car drivers. The fact that Poland is not generally tourist friendly (in terms of signage, use of English etc) is great for people like me who live here. It means the "great unwashed" tourists are only in places I try to avoid.
Life in Poland or anywhere else becomes better if you make these concious decisions. It isn't the easy, popular or quick option, but I would encourage you to stop at each majior decision, think and choose your path. It may or may not work out, but it is YOUR path. Decide not for ego, but for the right thing to do. It is harder than it sounds.
Let go of the outcome and enjoy (your chosen) journey. Anyway, enough of the philosophy. It takes time (and mistakes and experience) to be wise and as the years go by, I am learning how little I really know.
It's a great world.
