In this life you need to suffer to get something

The only constant factor in your life that will always be there is yourself.
Everything on the outside can change.

It depends on what kind of a life someone wants.
Some want to stay home and watch tv and porn the whole day.
Some want to go travel and see the world, meeting new people, try new things...

Everyone is at a different point of their journey

 

Agreed. Suffer now so you can relax later--but not too much, you don't want to miss the present either

 

Life is a one-time opportunity and it’s your decision how to live. Everyone thinks differently about life.

Yes, it is true that if you want something, you should suffer. This is the fact, everyone struggles every time to get what they want. By sitting at home, you can't achieve anything. So decide a goal and focus on getting success.

 

There's a price to pay for everything.

Not taking a risk is still a risk because you don't go for what you want.

Exercising has it's problems (time management / nutrition / dedication / work / etc), but not exercising also has it's problems (health issues).

There's always problems and some form of suffering in life. The question is what problems do you want in your life?

You can chill in your bed all day if you want, but do you think that doesn't lead to problems and suffering?
