Ahh, now you are realizing what it is that really matters. WEIGHT.

To help with that, always remember to look for the lightest weight example of whatever it is you need to take. Travelling light is not about doing without anything that you personally want to have with you. It is actually about 'having your cake and eating it too'. So for example if you want to have a keyboard, what is the LIGHTEST WEIGHT keyboard you can find.

In many outdoor stores, they will have weighing scales if you ask as it is common for wilderness backpackers to want to know the weight of every single item they choose to carry. Not so easy to do in other types of stores obviously although some people will actually carry their own weigh scales into a store to compare items. I tend to just hold one in one hand and one in my other hand and compare weight that way. Which one is lighter, NOT which one is cheaper is what I always look for.

Again in wilderness backpacking circles, some people can and do take it to the extreme. A long standing joke is that you should cut half the handle off your toothbrush and then drill holes in the remaining half to get the weight down to as little as possible and still not give up having a toothbrush. But not all that far fetch if you look at camping pot handles. Instead of each pot having a handle of its own, you use a handle that clamps on to the pot you are using. And yes, that handle has holes drilled in it to further reduce the weight of your cooking equipment.

The rule again is simple. Always look for the lightest weight example of the item you want to take.
