From Jim Hamilton:
Here’s some encouragement – it’ll only take 3 hours a day for about 7 years:
In his amazing book, The Outliers, author Malcolm Gladwell develops a challenge for us all. To become an absolute master at any skill, you must be willing to invest 10,000 hours. I call this the “10,000 rule”. Here’s the bad news. That’s 3 hours a day for the next 7 years. Every time I hear a master of any skill tell the story of his or her journey to excellence, 3 hours keeps coming up. Olympians train for 3 hours a day. Endurance athletes train for 3 hours a day. Master teachers obviously spend time in their subjects for at least 3 hours a day. Of course, this type of dedication is only necessary if your goal is mastery.
The Word of God is worth it, and the power of the Spirit is sufficient. Go for it by grace through faith in Christ.
This was in the comment section that I also found helpful: “I find Randall Buth’s materials to be the best out there for cutting down the mastery time significantly. http://www.biblicallanguagecenter.com”
