Honestly the first thing is that a solarpunk life is as can be lived today can never be perfect. That is due to the very simple fact, that our society is not perfect and a good quality life in a material sense depends on it. The key is to make our current world better. So the first thing is to look at your life and look at where you make the world better and where you make it worse and then do more of the former rather then the latter.

In terms of personal impact the big ones are:

• transport, aka less car and planes and more public transport, cycling and walking
• vegan diet or at least less meat
• home heating using less energy with insulation and using a somewhat low carbon heating systems like heat pumps or a better cooling system, with a properly designed or adapted house. Also the smaller the better.
• voting if you can and that includes voting for less bad canidates. That is honestly a big impact with very little actual work
• smart investing, if possible
• Become active in good projects in your community, if only in a very limited way. There are always some social, enviromental and so forth projects going on
• change to a more usefull job, that is 40h of your week, so if you can it can have a massive impact
• reduce, reuse, recycle that is a really usefull thing. Less stuff means less work, reusing and recycling also means less capitalist exploitation, most importantly of you.
• Also really important to transform your life in a way to give you more options. The key is to become economically as independent as possible. The key parts for that are simple living, aka buy less (new) stuff, wealth and different income streams.

It is reall hard to say what is easy, as we just do not know your current lifestyle and resources. If you own your home for example chaning the heating system is relativly easy, but if you rent it might be impossible, but if you live in a flat in a big city, going car free is easy. It all depends and we can not decide for you, but you have to solve that one yourself. Living a good life is not easy, that is unfortuatly the truth.
