A thought pattern$($s$)$ reflecting the $"$Be Proactive" habit would include:

a$.$ I refuse to be a victim of my circumstances$--$ I may not control circumstances, but I control my response to them.

b$.$ Covey's book has helped millions and been a bestseller since $1989.$ If I go through this book and am not changed in a major way, it is because I have CHOSEN not to invest in the process Covey outlines.

c$.$ Bob Knight once said, $$Everybody has the will to win, but very few have the will to do the upfront work it takes to be in a position to win". I choose to do the work it takes to build my personal leadership skills.

d$.$ All of the above.
