Owning a business is something I have always wanted to get involved but somehow reluctant due to that fact that I may encure  losses but from what you have just said I must say I have been encouraged .Since you are situated at the school environment it will help students do their work easily without any incoveniency, and also you have helped reduce the rate of unemployment in our community,nation and world at large even if it's just one person working for you.Your machine got bad and you repared it shows how determine you are and not tempted to give up as my case would have been if I were in your shoe but with what you have said I can now go into business without the fear of encuring losses knowing that there are ups and downs in business,time to gain and time to lose.Thanks for this post @breeze,I will recommend some of my folks there at bambili to petronize your business.I'm happy I read your post,so encouraging.God bless your husle.
