I've heard from many known successful entrepreneurs that second-time founders have acquired the skill to execute ideas, what first time founders lack.
It's my case, [I have some early ideas](https://publish.obsidian.md/louis030195/Ideas/Ideas) but not yet sure how to properly execute them.
As a technical person, I can create MVP(s) quite easily. This can be a useful step, but I don't want to waste my valuable time, do you have any recommendations on resources that explain how to properly execute of the ideas?
That is the true magic of entrepreneurship. And no, there isn't a formula because every possible idea has a completely different set of available resources and motivations. Execution is not a skill you acquire through experience because every enterprise is different. What you get practice at is following a standard set of steps you take to discover what will work.
Creating an MVP only applies to a small sub-section of product types. And you should never bother writing a single line of code until you have validated your marketing strategy. So there's your first clue, or at least your first step. Go through the process of building and then validating your marketing strategy. This research informs entrepreneurs who their audience is, where they are, under which conditions will they spend what money, how to reach them, and more. Without that information you can't judge whether your idea has real potential to be a business, nor will you understand the model under which your business needs to operate, what resources will be required, and if you still want to do it knowing all that.
Execution following validated strategy is most likely to succeed over any other path. So you're right, don't waste your time on ideas that aren't businesses. There is a lot of information available about the steps for building and then validating a marketing strategy. Too long to type every time someone asks. But it starts with making a list of every assumption you have made, then testing each individually.
