We make a lot of choices out of convenience, and a lot of choices to promote convenience. The problem is that not all convenience is the same. There is immediate convenience which seeks to avoid effort now, and long term convenience that seeks to consistently reduce effort over time. I realise that I have learned in my life to choose the first form of convenience, often at the expense of the second. Buying cheap disposable razors is easy on the wallet today but is a commitment to an ongoing cost. Buying a single razor that you can use every day for years, with minimal cost, could be cheaper over time but will also result in a better experience every single morning.

Of course I chose option 3, and don't own a razor.

Wealth consists not in having great possessions, but in having few wants.

For me, moving from PC to a Mac was this kind of decision, I opted for what I find is a better day-to-day experience and something that will continue to serve me well for a long period. I could not have come to the same decision if I was still a bleeding-edge computer gamer; these kinds of choices must account for all of your needs, and all of our needs are different.

For those things we need to own and make use of, I also believe it's not only almost always possible, but also always important that we enjoy them. There are as many small reasons to take a little pleasure from something as there are things that we have; because you love the smell of a particular hair product, or you're glad you took the effort to find an ethical, sustainable product. It doesn't matter what makes you happy, but if something has to be a part of your life then it probably should make you happy in whatever small way it can.

This isn't to say cost should never be a factor. It is obviously important, we might all love to own an expensive luxury car, and know exactly which model would be ideal for our needs; most of us will probably not be able to dedicate the finances to purchase one however. These choices have to be within our means and in accordance with our resources. Some things just aren't worth the cognitive or financial investment. If it's an object that doesn't get used often, or is there in case of emergency, then you don't necessarily want to invest your time or more money than you absolutely have to. There are many things to which we give little consideration, that we choose because we always have, or because it doesn't cross our minds that we might be able to make a little improvement.

Perfection is achieved, not when there is nothing more to add, but when there is nothing left to take away.

A consideration that we are always steered away from tends to be that of 'enough'. Marketers love to sell us features; having more of them, or having features that the competition do not offer is the most common quality one brand uses to set itself apart from the many other's like it. Look at all of the things that you could do with this thing! The minimalist approach is to consider what you need, and to an extent what you want or what you'd like. The perfect thing does those and nothing more. Features are expensive, and if they're not expensive in monetary terms then they are expensive in design, quality or cognitive terms. Compromising the things you need for the things you don't want is counterproductive, and there's little point bearing the cost for a feature that you don't find useful. These things said, 'enough' is the best reason to find something with more comprehensive features, where the solution you have falls short.
