Of course. The basic skills and cooking experience of a chef can't be learned in a day or two or even a year or two. It takes years of practice and accumulation. If you want to be a chef, you must be psychologically prepared, but if you are interested, you will not feel tired, but you will enjoy it! If you can afford it, you will go to the training class faster, but you can't learn well because of time! Being an apprentice in a restaurant will be tiring, but there will be time for you to practice your basic skills. Plus, you will study and practice hard, and your cooking experience will be greatly improved. In this way, you can learn to cook well. Most importantly, you don't need a lot of money, because being an apprentice is paid and you can get food, but the time cost will be higher!
