Time [wasted]

Every day is spent waiting. In the morning you wait for the bus, or you wait for a metro, or you wait in traffic, or you wait to cross the street. Then, you arrive at your location and sometimes you wait for an elevator, or you wait in line for a coffee. Sometimes you have to make a phone call in which you have to wait for the person to answer or, you have to wait on hold while listening to "elevator" music. In life, you are waiting for things to get better or waiting for something to start, or anticipating an end (which is really waiting) or waiting for that new job, new look, new lover, next paycheck to arrive.
People always say "live life to the fullest" or "enjoy every moment". I would like to know how. Have those people figured out their career goals? Have those people got jobs in which they are constantly satisfied with what they are doing every minute? And do they all have money? Are they able to "live life to fullest" because they can fly across the continent tomorrow and have a snazzy vacation?
I know it's probably one of those attitude things. Be positive in the moment and enjoy what's there, instead of worrying about what you're waiting for, where you're going, what you're going to do next or what's going to happen if you don't do this/that or the other thing.
I just think that the ability to live life to the fullest is for retired/or rich people. Who has the time really to just drop everything? Most people are too distracted with their day to day to "live" life. And of course we are, we work hard, we get paid little and there are thousands of stressful little events that keep us from enjoying what few years we have on the planet.
And imagine for instance, you've got a great job, you love going to work almost every day, the stress it brings is productive and healthy and the job resulted from 4-10 years in a post secondary institution. You are in the career world, doing what most people wish/are striving for. So, you've got the career and maybe you've got a partner and maybe you've got children but now, do you have any time? Do you have time to do all the things you would love to do?
Probably not.
It's never the right time. There's never enough money. There's always a reason not to.
I just find the world depressing. There are thousands of things to see and do and I'm jealous of every single person who gets to see some of it. It's all just slightly out of reach while we wait for the time when dreams come true.
