Self help - the best (& fastest) help you can get.
The consequence of going trekking, untrained is not new. Worse if you have no idea what to expect. It's ok to go but know humulity and leave the gungho mentality behind, or learn things the hard way. Sometimes, a "positive" attitude can do more harm than good. You want to do everything and anything that comes along, and you want to have your cake and eat it.
"Someone" will look after me, one may think. But because you didn't do something, "someone" had to do it for you. Sometimes, I think we tolerate too many bad habits that it encourages them to form. Things get taken for granted. Whatever role we play, each of us have our responsibilities and obligations to fulfill. Yes. What I mean is, the paying customer is not always right. Because, your own well-being is at risk. Someone will have to bear the risk for you if you do not. So, you had your cake and ate it. You forgot to ask how much it cost the "someone" who had to pay for you. I guess there is really no free lunch in the world.
"Someone" will look after you, only if they can look after themselves FIRST. If you don't learn to look after yourself, who will?
