Hey Tommy,
As an 'ol timer, I'll just offer some "food for thought" from my experience, and I'm sure you will get many personal opinions and suggestions from the really superb group who linger here.
The family is the ultimate unit. You have to make all decisions based on the situation and your expectations to have both a home and work life so they both can co-exist in harmony. A family "sit-down" to discuss your options, financial needs, home life/responsibilities, and emotional stability all have to congeal to maintain happiness, strength, & love within the family unit. Communications.....OPEN...HONEST....communications. Allow everyone to express their needs and hopes for each tomorrow. It will work.....If you allow it.
The job is the primary focus as it is the basis for your lifestyle. If you have to take a job that you know you are not going to look forward to doing, you are wasting precious time. You have to know the career you choose is what you WANT to do and LOVE to do. There are many families that accept and understand the careers that require mobility, or extremely long hours, and the absence from family life and the sacrifices are acceptable. They choose to live that style. Those who don't must be able to compromise to the satisfaction of all family members.
Teaching can be a rewarding career and allow you to pass on all your experiences and knowledge to give another the opportunity to become a productive member of the workforce. To instill the values, honor, and work ethics you maintain to be successful to the youngsters entering the work arena can be quite satisfying.
As far as an "abrasive" mannerism/personality, there is nothing wrong with it if you know how to control it and not allow it to be detrimental to your focus. Patience is an acquired virtue....some get it....some don't. You will find patience will always work out to benefit all involved. I, too, have the same "abrasiveness" in my character, but have tempered it thru wisdom, understanding, and patience.....TO A POINT!!! I don't and won't tolerate those who show no interest, lack of motivation, or negative outlook on everything presented to them. I live and work by honor....ethics....and a positive mindset.....has never failed me.
Anyway, I hope my words will allow you to look within and with the value of your family's input, will help you determine your best choice and succeed in you endeavor.....Good Luck...Denny
