You Don't... but you could!
I find so many people nagging about all the things that they do not have, or cannot do or have not had the time to do.
Give over already!
You have to decide that you will, then you have to put your time and effort into it and stop watching TV or surfing the net, or browsing junk on your phone and you will find that one day at a time you are moving towards your goals.
You don't because you have not given it enough thought, and most of the things that you nag about are passing whims, not really things that you want to do.
