These folks are amazing. Don’t ever say they are old. Don’t you wish you could do what they can when you’re 70? Not to late to start if you adopt the lifestyle promoted at Kanpsack Treks.
It’s good to have friends join you in activities like this, but in certain societies which are often too busy with other priorities, you need to be able to do things alone. Don’t wait for others to take the lead. Don’t wait for everyone to be free to join you. It doesn’t matter if others don’t share your interests. If you have to do it alone, just go ahead. Seize the day.
