Started using this approach in Bannerlord and I am enjoying it more since. The initial loss of progress is annoying but if you persevere and don't yield to the temptation to load, then the delayed success feels more satisfying and earned when you do achieve it. It also tends to make a game last longer so you get more out of it.
Regarding guides, I avoid them like the plague. Too much information about a game is toxic, especially if it includes exploits and/or cheats. While searching for something about the Bannerlord economy the other day, I stumbled on a reddit thread and the most upvoted post was from some know-it-all ****** proudly announcing that you can break the game with
smithing and get fast infinite money. I quickly clicked off of the page but it was too late, the poison knowledge had already been absorbed into my brain. I really don't understand why it isn't just common courtesy to spoiler such information. I never intend to use this exploit but just being aware of it has reduced my enjoyment by some degree, because it trivialises the struggle for wealth - a core aspect of the game.
