You’re never too old to learn some new tricks. It’s important to keep up with the technology and the means of communication of your times. Don’t make excuses like you’re too old, you don’t like Facebook, that’s just for kids, etc. If you want to communicate to others, and that is what God has called us to do, then you need to use the current means of communication. Just get over your bad self and do it!
Look at me! I’m over 40 years old and am learning WordPress so I can fulfill God’s calling in my life. WordPress is a means of communicating to my target audience. Of course, I wish I could just get a download and instantly know everything I need to know. But there is a learning curve - the rate of a person’s progress in gaining experience or new skills. That means it takes time!
When you start out to learn something new, you learn just a couple things. But as you persevere in your quest to learn the topic or skill, you will use this knowledge to build on more knowledge. Continuing in this, you will begin to understand more and learn quicker. WordPress is a powerful tool with lots to learn about it, but I am committed to learning little by little and putting what I learn into practice!
What has God been asking you to step out and do? What do you need to learn in order to do it? Just do it! Research it on the internet, buy & read some books, and take any other action He directs you to. You can do it!
