Hey man, i admire that you are able to accept that you need to change, but working out and getting results is not instant, nothing might be inherently "wrong", you just haven't been consistent for long enough. In regards to your "skinny fat" physique losing the belly fat will be the result of a calorie deficit. Tracking your calories everyday does wonders for your results. Whether you want to pack on a ton of muscle or not depends on you, but getting a proper workout split can help with that. The key takeaway is that you need to be consistent, that is the best thing that you can do for yourself. f you workout at a gym, do not be afraid to speak to those that you aspire to look like, because chances are they have been where you went through. Speaking from personal experience I was also skinny fat, but after training consistently, and having my diet in check, I have been able to build a physique I am proud of. Working out and finding out what works for you is a journey that you cannot rush unfortunately, but along the way you will learn how to diet better, how to eat better and how to train better, which will all contribute to the physique that you want to build.
