My friend likes playing football. I told him, "I think practising with me is effective than by yourself (our practice with me is effective than alone). (So we had better increase the number of times we meet. But the time we meet at one time may be short instead.) However, meeting at once may be short so we had better increase the number of times we meet instead."
