I'm only ten years into my flying so take my tips for what they're worth. I don't really do the STOL thing or back country strips as I'm mostly a float guy so my advice is going to me more about flying remote country.
1. Be a student of weather. Watch weather, learn weather, learn to predict weather and what the weather that you see means for where you are and where you're going. In BC anyway, the weather services are sparse. I just watched a little Trent Palmer video where he's fishing up in one of my favourite hunting areas and he made note of the fact that there was no weather services within 100 NM of them. This is true for a lot of BC. If your flight starts somewhere with comms you can get an overview of what the satellite shows the FIC guy but that's really it. This gets even more pronounced if you move North into the Territories.
2. Always have a working ELT in your plane at the least. This is required in Canada but somehow guys do go flying without. A few years back a trio of local idiots pancaked a plane onto a Glacier not far from Whistler. The plane had no ELT. What could have been a total non-event turned into several days of searching and several nights and days for them sitting up on a glacier. They also weren't carrying any survival gear and i think the one guy was in a T-shirt and they cut up the interior of the plane and made the seats into makeshift shirts or something. For someone deliberately heading into the backcountry an ELT and an Inreach should be with you all the time. You don't want to set a plane down with a minor problem and then be stranded for a week because you had no comms.
3. Be mentally prepared and have gear with you to choose inconvenience in the name of safety. Choosing to set down somewhere and wait out weather, or avoid exhausting your fuel is a better choice than crashing in the wilderness. The choice is easier if you have the gear to make it a non-event and are mentally ready to make the call.
4. If you're flying along and a the situation is coming at you too fast, consider slowing the plane down. Drop down to flap range and put in a couple notches of flaps and stop flying so quickly into the bad weather or climbing terrain. The plane turns around tighter this way too, and if you've got room to let the nose drop during your 180 you can turn around really tight
