Before you begin a thing, remind yourself that difficulties and delays quite impossible to foresee are ahead. If you could see them clearly, naturally you could do a great deal to get rid of them but you can't. You can only see one thing clearly and that is your goal. Form a mental vision of that and cling to it through thick and thin.
When I see teenagers out in public with their families, holding back, refusing to walk with mom and dad, ashamed to be seen as part of a family, I have to admit that I have acted that way myself, at times, with regard to my Christian inheritance. A hapless and mortally embarrassed adolescent lurked behind the sophisticated mask I wrote in my twenties: faith was something for little kids and grandmas, not me.
