Feeling stuck

I feel stuck today - hanging out in a holding pattern and waiting for things to happen.
Our cash flow is out of whack because our tenant is two weeks late with the rent. She called me at the end of last month and explained that she'd been off work for throat surgery - possible cancer of the larynx - and her paycheck was too short to make the rent payment. I agreed to her request that I hold her rent check until June 11 so her next pay period will cover it. However, it is now June 9 and I still haven't seen the rent check I'm supposed to be holding. Considering my experience with my previous tenant, this makes me a little nervous.
Maria's birthday is Sunday and we still haven't settled on what she would like for a present. At the moment, it's narrowed down to $150 worth of quilting supplies - which comes in a special shopping bag that gives her the status of a Bag Lady at the quilt store and confers special privileges and benefits - or a personal DVD player for use while traveling.
We're also trying to blast her loose from her job for a vacation in the West. The plan is to combine a photo expedition to the canyonlands of southern Utah and Monument Valley with a visit to our friends in Alma, Colo. The only problem is that Maria is sometimes calendar-impaired and inadvertently schedules multiple activities for the same day and time. She also has a hard time asserting her right to a vacation. Since we're planning to cover a lot of ground in a short time, carrying photo gear and in probably hot weather, this will be done in the Subaru Forester rather than on the bike.
I ordered 512 megabytes of memory for my computer this week in hopes of making Photoshop CS run faster and be more manageable. I'd love to be installing it this afternoon, but it didn't come in today's mail.
As soon as I get the memory boost, I can start ascending the learning curve of the Creative Suite of programs that is the CS in Photoshop CS. It includes the tools to make the website Maria has been wanting for our photography business and I'm eager to get going on it.
We've got our first "paying" wedding scheduled for June 25. We're only charging $200 plus prints because the father of the bride is a police detective who is also an excellent source for Maria and her newspaper.
We're scheduled to have a phone conversation tonight with Rich, probably the best photographer on the major daily where I used to work, about the dos and don'ts of the wedding photography business. Rich has been doing weddings as a sideline for a few years now and seems eager to share his knowledge and experience with us.
We're also signed up to have a booth in a community arts fair on July 9 - a scant 5 days after we get home from vacation - so we need to figure out what to include and get most of the preparatory work done before we leave.
When I went out to check the mail Monday morning, I found two guys from a tree service standing in the alley that is our driveway, looking up at the three trees the town council finally admitted responsibility for. They looked pretty intimidated by the prospect of working on three 65-foot-tall maple trees that are within 20 feet of my house. At least now I know that the town council followed through and contacted a tree service about the job. I worried that they would just let it fall between the cracks until a storm puts a tree on my house. Of course, now that they see the scope and complexity of the job, they may never come back. We shall see.
