What do you want to achieve in your life?

I believe in the Chinese saying that we should refine ourselves, put our family in order, build a healthy society or country, before we can bring peace to the world (in that order).

If we are not sure what we want for our lives, it is difficult to communicate anything worthwhile to our families, much less to the society at large.
Similarly, if we cannot help our families find their fulfillment, how can we really convince the world that we can live at peace?

Therefore, I think it is useful for us to set our vision and mission for our personal lives.
If your spouse sees the value in this (after seeing yours in action), you can also craft one set for your family.

A vision sets out who we want to become, and be remembered as.
A mission sets out the things we want to do, based on the vision.

We can then draw out a few strategic thrusts by focusing on the mission, by which our daily lives would be governed by.
After that, we can set goals for ourselves.
There are long term goals (5 years) and short term goals (1 year).
They are based on the strategic thrusts too.

This allows us to live our lives with purpose, and focus.

I would like to present my version.
This is not the best version ever, but I hope it would inspire you to do something similar, so that you would live a purposeful life.

My vision is:
To be a role-model Christian man in everything I think, say, and do, so that others are inspired to live meaningful Christian lives.

My mission is:
To bring others to the saving grace of our Lord Jesus Christ, and assist the fulfillment of God's will in their lives.

I managed to write out 5 strategic thrusts:
1. Be an exemplary son to the Father, and brother to the Church
2. Be an exemplary grandson, son, brother, husband, and father
3. Be an exemplary mentor to my peers and the young
4. Be exemplary in my career
5. Be all things to everyone, so that some may be won

I would not list my goals here, because those change with time, and would not apply to you.
However, you can definitely find resources on the Internet to help you write out goals relevant to your lives.
Just bear in mind what you want to achieve in 5 years, and then work backwards, by breaking down those long term goals into manageable short term goals (1 year).

May the Lord grant you favour in this.

How should we respond when we are discouraged in doing good?

The Lord has planned good deeds for us to do.

Sometimes, no matter how hard we try, certain situations are beyond our help.

At other times, even though we help someone, and the person gains from our assistance, the person may turn out to be ungrateful and even backstabbing.
The person may have counted our offences against us, more than our willingness to help in the situation.
The person may also feel a false sense of accomplishment and pride at the achievements, as though the person is "self-made".

You know that whatever good deeds we do, we do it as unto the Lord, not counting the possible gratitude and rewards in this life, but with a heart of pure goodness to exclaim the glory of God.
Even so, we do feel disappointed, don't we?

Whatever it is, I encourage you not to give up doing good (not necessarily always to the same person), because you will reap the harvest in the long run, if you do not give up.

Besides, it is not about the others and you.

It is strictly between God and you.
