Stop as you need to. Replenish water as much as you need. Eat and munch from time to time along the hike. Hire a porter or a mountain guide (both can be the same person) to be with you all the time is the best choice if you are moderately fit (cannot run up and down the mountain type).

Waterproof jacket and pants are important. Keep yourself as warm as possible. Don't underestimate the temperature. No heroic actions or ego needed, make sure you can reach to the summit is not only your physical condition (train for it no joke) but also your mental condition at that point. Turning back when you need to is not a shameful decision. It is a live or death decision. So turn back when you know you cannot. (Very costly when porters need to bring you down. Can reach to RM16-20K depending on your weight and condition.

Train hard. Don't forget to train your arms too. To reach the peak, a lot of robe climbing needed which need much arm strength.

Whatsoever, please stay safe and be wise to turn back whenever and wherever you are. Your life is more important than summiting.
