There is no real rule when it comes to meditation and to how long you should meditate for, it's really up to you.
As a general guideline, though, it's strongly recommended to start out small.
Start with short periods of time, such as 5-minute sessions once or twice a day, and build it up slowly.
It may seem like too little, but even 5 minutes a day of being mindful and meditating can have a huge impact on the rest of your day or night, depending on when you decide to do it.
The reason this is strongly advised is because sitting in meditation can be very difficult, much more difficult than many people actually think.
To sit down for a lengthy time period doing nothing but following your breath or listening to a sound can be a very strange sensation, and one that is simply difficult to do.
Starting out with long sessions is a very risky way to start this practice since you can risk losing motivation for the practice once you see that sitting for 30 minutes or longer is difficult.
Start out with short, 5-minute sessions once a day, then add another session when ever you can. Once that gets easy, you will see that you can naturally progress and add more time to each session. Eventually, you will make your way to those 20-30 minute sessions.
Progressing slowly helps ensure that you do not lose motivation for the practice, and that you don't stress yourself out about not being able to meditate for long periods of time.
There is a saying I try to live by: Don't do to others what you wouldn't want done to you.
And this is what frustrates me and upsets me, that others who also try and live by that saying or at least agree with it, do the complete opposite.
Not saying that mistakes don't and won't happen, they do and they will, we are not perfect, and that is part of what is beautiful about us humans.
But, when people purposefully do things to others, that they themselves know they would not want done to them, but consciously make the decision to do those things anyway, that is what gets to me, that is what upsets me.
This is actually a difficult question to answer, as both can lead to great experiences, even though they may seem like major negative things.
Having too much money and relying on that money can keep you in a very comfortable and safe zone, limiting the adventures and excitement in life.
Being alone allows you to better understand yourself, and to appreciate your own company, rather than relying on others.
People tend to rely on money and on other people to help them feel happiness, believing that those two are conditions to living a full and happy life.
Being alone or lonely isnt always a negative, being broke can cause you to go down new paths you may not have thought of if you had more money.
But, of course, its all a matter of perspective and how each of us define broke and lonely.
I think much of the youth are much more intellegent than they get credit for. I believe many of them could make a great change.
But, of course, its very difficult to say since there is such a great diversity in the mindset of the younger population.
