This is one of my favorite prayers. It was written by Thomas Aquinas. I often pray this as part of my morning devotions.
For Ordering a Life Wisely
O merciful God, grant that I may
desire ardently,
search prudently,
recognize truly,
and bring to perfect completion
whatever is pleasing to You
for the praise and glory of Your name.
Put my life in good order, O my God.
Grant that I may know
what You require me to do.
Bestow upon me
the power to accomplish Your will,
as is necessary and fitting
for the salvation of my soul.
Grant to me, O Lord my God,
that I may not falter in times
of prosperity or adversity,
so that I may not be
exalted in the former,
nor dejected in the latter.
May I not rejoice in anything
unless it leads me to You;
may I not be saddened by anything
unless it turns me from You.
May I desire to please no one,
nor fear to displease anyone,
but You.
May all transitory things, O Lord,
be worthless to me
and may all things eternal
be ever cherished by me.
May any joy without You
be burdensome for me
and may I not desire anything
else besides You.
May all work, O Lord,
delight me when done for Your sake
and may all repose not centered in You
be ever wearisome for me.
Grant unto me, my God,
that I may direct my heart to You
and that in my failures
I may ever feel remorse for my sins
and never lose the resolve to change.
O Lord my God, make me
obedient without protest,
poor without discouragement,
chaste without regret,
patient without complaint,
humble without posturing,
cheerful without frivolity,
mature without gloom,
and quick-witted without flippancy,
fear You without despairing,
truthful without duplicity,
do good works without presumption,
reprove my neighbor without exulting,
and – without hypocrisy – strengthen
him by word and example.
Give to me, O Lord God,
a watchful heart, which no capricious
thought can lure away from You.
Give to me a noble heart,
which no unworthy desire can debase.
Give to me a virtuous heart,
which no evil intention can divert.
Give to me a constant heart,
which no tribulation can overcome.
Give to me a free heart,
which no violent passion can enslave.
Give to me, O Lord my God,
understanding of You,
diligence in seeking You,
wisdom in finding You,
conversation pleasing to You,
perseverance in waiting for You,
and confidence in finally embracing You.
Grant that as penance
I may be afflicted by Your hardships now,
through grace I may rely
on Your blessings on the way,
and in glory I may enjoy You fully
in the Kingdom of Heaven.
You who live and reign,
God, world without end.
Amen.
