Short-term trading activity is the best option for beginners in trading activity in my opinion, because it perfectly explains all the laws on the market and explains the forming of dynamics of price direction. Actually, all the mechanics of the market can be understood only via short-term trading. Only when you understand these mechanics, you will be able to choose between long-term trading and short-term trading. As for the advice, I would advice you to learn basic notions in technical analysis and try to create your own strategy which you should test on demo account.
